MAGNETIC ENGINE OR MOTOR.

SPECIFICATION arising part of Letters Patent No. 689,483, dated December 2'4, ieoi.

Ap licant filed Ma 23, 1901.-

To all whom it may concerri'; Be it known that I, RAYMOND R. GILMAN, a citizen of the United States, residing in Melrose, in the county of Middlesex and State 5 of Massachusetts, have invented an Improvement in Magnetic Engines or Motors, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. 7

This invention relates to a magnetic motor or engine in which a driven member is provided with one or more magnets and is actuated by a'driving member provided with a movable magnet. The driven member may have imparted to it a rotary or an oscillating motion, and ,the driving member may be given a rotary movement, so that the poles of the magnet carried by the driving member may alternately attract and repel the poles of the magnet or magnets carried by the driven member to produce motion thereof. These and other features of this invention will be pointed out in the claims at theend of. this specification.

Figure 1 is a plan View of one form of a magnetic engine or motor embodying this invention; Fig.2, a side elevation ,of the engine shown in Fig. 1; Fig. 3, an end elevation of a modified engine; and Fig. 4 a side eleva tion, with parts broken out,'of the engine shown inFig. 3. Referring to Figs. 1 and 2, 6t represents a shaft having bearings in a baseb and an arm 0 attached to a framework d. The shaft a constitutes the driven member of the magnetic engine and in the present instance has fast on it a disk e, to which is secured a series of radially-projecting magnets, herein shown 40 as four in number and lettered f g h 'i. These magnets are represented as permanent magnets and are secured to the disk 6, as by screws j, so that like poles are in the same horizontal plane, and with these magnets cooperates 45 a magnet 70, also represented as a permanent magnet and. which is carried by the driving member, which latter is shown as a rotatable shaft m, having bearings in suitable uprights n on a base 0. The magnet 70 is set with its 5o poles in a vertical plane and in close proximity to the path traveled by the poles of the Serial No. 61,494. (No model.)

permanent magnets carried by the driven member. The shaft n may be rotated by power or, as represented, by means of a bandle p on a crankor disk 7", and as the said shaft is rotated the permanent magnet 7c is turned so that its poles N S will act on like poles of the magnet f and repel the same, thereby forcing the magnet-faway from the permanentmagnet Zr and causing the shaft 0. to be rotated. v

The rotation of the shaft a moves the magnet g toward the magnet is, and as the mag'- net g approaches the driving-magnet 7a the latter is rotated so that one of its poles, as N, cooperates with the south'pole of the magnet g and attracts the-latter until at or about the timethe magnetg is in substantially the same plane as the magnet is, whereupon continued rotation of the magnet It presents like poles 7o .to'the poles of the magnet 9, thus causing a repelling action, which produces ..continued movement of the magnet .g andthe shaft a.

The attracting and repellingzaction of the driving-magnet .70 upon'eaclnof the driven 7 magnets is continued as long as it is desired to rotate the shaft a. By rotating the driving-magnet lc in the reverse direction the shaft a mayberotated in the reverse direction. Thedriven shaft may be stopped by stopping the driving-magnet 70 with its poles opposite unlike poles of a driven magnet, as represented in Fig. 2. In Figs. 1 and 2 I have shown the invention as embodied in an engine in which the driven member has imparted to it a rotary motion; but I do not desire to limit my invention in this respect, as it may be embodied in an engine-in which the driven member is oscillated, as represented in Figs. 3 and 4, 50 wherein the driven member is shown as a walking-beam or lever 2, mounted on a shaft or pivot-rod 3, supported in uprights 4'. The lever 2 has attached to it near its opposite ends two permanent magnets 5 6, vertically' 5 movable in suitable guides 7 8, erected upon a hollow base or support 9, which contains two driving permanent'magnets 10 11, secured to'shafts12 13, which are rotatively supported in suitable bearings 14 15, secured to a cross-bar or partition 16 within the hollow base or support. The driving-magnets 1O 11 are arranged in substantially close proximity to the driven magnets 5- 6 .when the latter are in their lowermost position, and by rotating said driving-magnets their north and south poles may be brought substantially into line with unlike poles of the driven mag nets 5 6 when it is desired to produce motion of the walking-beam or lever 2.

As represented in Fig. 4, the driven magnet 5 is in its lowest position in close proximity to the driving-magnet 10, Whose poles are in line with or opposite unlike poles of the magneto. Now by rotating the shaft 12 the driving-magnet 10 is turned so that its poles are changed with relation to the poles of the magnet 5, and as said change is effected the magnet 5 is repelled by the driving-magnet, which repulsion is at a maximum when the poles of the driving-magnet are in line with like poles of the driven magnet. The repulsion of the magnet 5 elevates the end of the lever or Walking-beam to which the said magnet is attached and lowers the opposite end of said lever, thereby bringing the magnet 6 nearer the driving-magnet 11, which is turned so that its poles are opposite unlike poles of the magnet 6, thereby attracting to it the magnet 6, and thus assisting by its attract ive force the repelling force of the magnet 10. At or about the time the magnet 6 has reached the magnet 11 the latter is turned so as to reverse its poles with relation to the poles of the magnet 6, and thus cause the magnet 6 to be repelled, while at the same time the magnet 10 is turned to reverse its poles, and thus attract its cooperating magnet 5. In this manner an oscillatory movement is imparted to the driven member or lever 2, which movement may be converted into a rotary movement in any desired or usual manner. In the present instance this conversion is effected by means of an eccentric-rod 1'7 joining the lever 2 to an eccentric-pin 18,movable in a slot 19 in adisk 20, fast on a shaft 21, provided with a pulley or Wheel 22.

I have herein shown a simple form of apparatus embodying my invention; but I do not desire to limit myself to the particular form of apparatus shown.

I claim 1. In an engine or motor of the class de esd is scribed, the combination with a driven mend ber provided with a permanent magnet, of a driving member provided with a permanent magnet having its poles cooperating with the poles of themagnet carried by the driven member and movable with relation thereto to produce movement of said driven member; substantially as described.
